Hi I am running a digital ocean ubuntu 14.04 image. For some reason uname cmd reports 3.13.0-24 when the actual kernel should be 3.13.0-62.
bailey@bailey01 -> uname -mrs
Linux 3.13.0-24-generic x86_64
My system is up to date with the latest pkgs. The later kernel headers are available
bailey@bailey01 -> dpkg -l|grep linux-headers
ii linux-headers-3.13.0-62 3.13.0-62.102 all Header files related to Linux kernel version 3.13.0
ii linux-headers-3.13.0-62-generic 3.13.0-62.102 amd64 Linux kernel headers for version 3.13.0 on 64 bit x86 SMP
ii linux-headers-generic 3.13.0.62.69 amd64 Generic Linux kernel headers
/boot/ has the correct files
bailey@bailey01 -> pwd;ls -l
/boot
total 29740

I ran an update on the grub config using two different commands (grub-mkconfig and update-grub)
sudo grub-mkconfig -o /boot/grub/grub.cfg
Generating grub configuration file ...
Found linux image: /boot/vmlinuz-3.13.0-62-generic

Found memtest86+ image: /boot/memtest86+.elf
Found memtest86+ image: /boot/memtest86+.bin
done
I rebooted the server after the mkconfig.
This started when I tried to configure iptables and received errors pointing to this erroneous kernel version
bailey@bailey01 -> sudo iptables -L
modprobe: ERROR: ../libkmod/libkmod.c:556 kmod_search_moddep() could not open moddep file '/lib/modules/3.13.0-24-generic/modules.dep.bin'
iptables v1.4.21: can't initialize iptables table `filter': Table does not exist (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.
A google search has not returned any links that were helpful.
Help me Obi Wan Kenobi you are my last hope 8-)
Cheers

Ran into that exact same problem on multiple occasions (at least on the Ubuntu kernels). It always surfaced with ipTables (and hence, CSF firewalls). For us, the short answer was a hard restart after the update process. Simply rebooting the droplet would not solve the issue.
(This assumes you’ve actually installed the updated kernel. We used a “manual” update process. An example can be be found all over StackExchange, including this fragment:)
Go here: http://kernel.ubuntu.com/~kernel-ppa/mainline/
Download 3 (maybe 4) debs to a folder somewhere:
linux-headers-VERSION-NUMBER_all.deb
linux-headers-VERSION-NUMBER_amd64.deb
linux-image-VERSION-NUMBER_amd64.deb
linux-image-extra-VERSION-NUMBER_amd64.deb # if available
Install the debs with whatever package manager front-end you use (is gdebi still around?), or use these commands:
cd /path/to/folder/where/you/put/the/debs
sudo dpkg -i *.deb
Note: this will “break” the ability to utilize the D/O droplet console to manage your kernel (under “settings --> kernel”)
@tmbailey123 did you ever get this solved? I have a similar issue on 15.04
gabriel@host:~$ uname -r
3.16.0-28-generic
but it should be 3.19
Kernels do not upgrade automatically to a next major version (like 3.13 to 3.16) through routine updates. You can do it manually by running
sudo apt-get install linux-generic-lts-utopic
If you want to update the kernel to 3.19 use:
sudo apt-get install linux-generic-lts-vivid
You can read more about the HWE stack
After you are happy with the new kernel, you can remove 3.13.0-24 kernel meta-packages to prevent 3.13.0-24 kernels from updating. It can be done by
sudo apt-get remove linux-image-generic linux-headers-generic
